Abstract
The macroscopic electro-optic activity of organic materials is linearly related to molecular first hyperpolarizability of individual chromophores, chromophore number density, and the acentric order parameter describing chromophore order. When strong chromophore-chromophore intermolecular electrostatic interactions (e.g., dipole-dipole interactions) are present, the latter two quantities are not independent. In previous publications, we have demonstrated how electro-optic activity can be systematically improved by control of chromophore shape in chromophore/polymer composite materials and by the nanoscopic engineering of single- and multi-chromophore-containing dendrimer materials, where steric interactions and covalent bond potentials are used to inhibit centrosymmetric ordering of chromophores. In this communication, we demonstrate how doping a second chromophore into a chromophore-containing material can lead to dramatically improved electro-optic activity. This work also provides insight into the affect of surrounding lattice on solvatochromic shifts and line broadening that can lead to increased optical loss.
